I've written a small hierarchical clustering algorithm (for better or for worse). I'd like a quick way of visualizing it, any tooling ideas?
More powerful solution is to use R, but here you would have to invest some time in making conversion to the
dendrogram object (basically list-of-lists).
You can use PhyFi web server for generating dendrograms from Newick files. Sample output using your data from PhyFi:
While it's not a tool per-se, ascii art is a fairly safe option actually, and not as hard as it seems at first. It's not pretty, but it gets the point accross.
